In this embodiment of the utility model, there are multiple pallets 50, and the multiple pallets 50 are stacked. During the lifting process of the multiple pallets 50, the side wall surfaces of the multiple pallets 50 can be in line contact with the guide assembly 30. With this arrangement, the guide assembly 30 improves the positioning accuracy of the lifting of the multiple pallets 50, avoids the deflection caused by relative movement during the lifting process of the multiple pallets 50; and improves the smoothness of the lifting of the multiple pallets 50.

[0042] In the embodiment of the present invention, the supporting portion 230 may be a plate-shaped structure.

[0043] In the embodiment of the present utility model, the structure of the guide assembly 30 is not limited, and is specifically as follows:

[0044] See attached Figure 1 - Figure 3 In one embodiment, the guide assembly 30 includes a first guide rod 310 fixed to the base 10. Two sets of first guide rods 310 are spaced apart along a first direction on either side of the support portion 230. The contact areas between the first guide rods 310 and the tray 50 have a first curved surface structure, enabling linear contact with the sidewall of the tray 50.
